Single Bipolar Transistors Procurement Notes

Verify the specific suffix designation to confirm packaging type and environmental compliance. The AP suffix indicates ammo packing, while BP denotes bulk packaging. Halogen-free variants are available upon request by adding the HF suffix. Ensure procurement from authorized distributors to guarantee genuine parts and full traceability as per manufacturer guidelines.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -30V collector-base breakdown voltage is required. The BC328-40 variant provides an hFE range of 250 to 630, suitable for high-gain applications. Consider the TO-92 package constraints for thermal management given the 0.625W dissipation limit. Verify lead style requirements for PCB assembly compatibility.

Single Bipolar Transistors Part Context

This part belongs to the BC327/BC328 series of PNP transistors. The BC328 specifically differs from the BC327 by having a lower collector-base voltage rating (-30V versus -50V). Both share similar current and power capabilities but are distinguished by their voltage ratings and corresponding hFE classifications.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other BC328-40 variants from different manufacturers. Cross-reference electrical parameters such as VCBO, IC, and hFE ranges to ensure functional equivalence in existing circuit designs.
